made it all up for no actual reason…

For me, it's not that information is 'made up'. It's a question of emphasis and one-sidedness. And there is a reason for the dominant narrative. You said:

even when communists are not a political threat…

But this is false. Communists are and always will be a threat to liberals and fascists. They can be slandered, tortured, imprisoned, misrepresented, and killed. But they will never disappear. They will never stop fighting. And they will never be finally silenced. That is why capitalists spend so much money, time, and effort distorting history. This is the reason you're looking for.
